The Eskimo nebula is a fine object for each size of optical instrument. For this observation I’ve used an 11” SCT and have noticed the fine detailed structures within this planetary nebula for the first time – using averted vision, high magnification of 600x and an excellent UHC filter.
Details:
• Eskimo Nebula (NGC 2392 / Caldwell 39) in Gemini
• Media: graphite pencil on white, scanned and inverted (GIMP2)
Observing notes:
Central star is easily direct visible within a round glow. Using averted vision a near-circular ring is clearly visible with some hints of variable brightness. The outer halo becomes gradually fainter and mottled using averted vision, containing some arc-like structures. Impressive view!
Pelayos is relatively close to Madrid , tonight stellar magnitude is 5.1 , not being the best conditions for observing deep sky objects , but incredibly the NP in this place have a brightness nearly comparable to the best skies I have seen.
The nebula is easy to locate as it is easily distinguished in the 30mm eyepiece that gives a real field 2 and 40x magnification .
With 40x appears bright , big and round. The less dense central region being surrounded by a thick contour brighter , especially in the low part, and cutting at two opposite ends , one very clearly , sounding the form of a ” horseshoe” .
With 80x lost denser areas , disappearing horseshoe shape , but gives an incredible feeling of great size, and clearly distinguish at least two starlets inside.
The design and perform observation with 40x decide better appreciation for density variations .
Indispensable observation filter and side view to appreciate the details.
New 10” dob telescope. Object Elevation +24º. Male 5,1. 14º C. Moisture 50 º/º.
M76 is a planetary nebula really awesome observed from a dark skies and with a good telescope aperture. Two distinct sections, one brilliant and compact, the other more extensive and diffuse. A very attractive nebula to be seen on a dark night and away from any light pollution.
For more details of my observation you can visit my blog:
I submit to you a sketch of Jones 1 or PK104-29.1. After an evening of excellent seeing & pursuing dim & stellar planetary objects, this was a treat to finish the evening with. The sketch shows my observation using OIII & NPB filters.
Jones 1 is a 12th to 15th magnitude (depending on source referenced) ~5’ planetary nebula located in Pegasus. It appears very dim but takes on much more detail with the use of OIII or NPB filters. It appears somewhat circular with the brightest rim to the NW, however another rim of brightness appears to the SE at times. With prolonged observation there is a shimmering & shifting to the brightness within the broken ring. A few dim stars appears embedded with averted vision. My profession is in the medical field and I was struck by a first impression of a 3 dimensional corpuscle!
